LUBR'ICATOR.

SPECIFICATION forming part of Letters Patent No. 456,714, dated July 28,1891.

Application filed February 16, 1891. Serial No. 381,690. (No model.)

To aZZ whom it may concern.-

Be it known that I, EDWIN D. BANGs, a citizen of the United States, anda resident of Milwaukee, in the county of Milwaukee, and in the State ofW'isconsin, have invented certain new and useful Improvements inLubricators; and I do hereby declare that the following is a full,clear, and exact description thereof.

My invention relates to oil-cups for lubricating locomotive and otherengines; and it consists in certain peculiarities of construction, aswill be fully set forth hereinafter and subsequently claimed.

In the drawings, Figure 1 is a vertical central section through one ofmy improved devices, the oil-cup being shown in position to lubricateone of the drive-wheel pins. Fig. 2 is a plan view of the said oil-cupwith the top removed. construction.

My present invention is an improvement on the device for which LettersPatent of the United States No. 414,278 were granted to me on November5, 1889.

A represents the cylinder of the cup, the upper part of which isexteriorly screwthreaded, as shown at a, for the reception of thecorresponding screw-threaded depending circular flange l) of the cap 13,which latter has an upwardly-extending central neck 0, having interiorscrew-threads for the reception of a corresponding screw-threaded plugD, having an internal recess d on the under side, but, unlike myprevious patent, without any vertical or other air-opening through saidplug, and below said neck C the cap R has a central hopper-shapeddepression B, with a central opening I), but without the diagonalorother vent shown in my said prior patent.

E represents a vertical column, preferably integral with the inside ofthe cylinder A, so as to be adjacent to the wall thereof, and thiscolumn is provided with a vertical channel 6.

E represents the exteriorly screwthreaded nipple, and this is here shownas projecting from beneath the center of the cylinder A.

This nipple is provided with a central extension or downward projectionE of less diameter than that of the said nipple, the said nipple andextension being provided with a vertical channel 6', which is connectedto the de Figs. 3 and 4 are details ofscribed channel 6 by means of ahorizontal or other channel 6 preferably bored from the side of thelower part of the cylinder A, the outer end of said channel 6 beingfilled up by a plug 6 as shown.

it. This plate has two end holes 72., correspending to the end holes ofthe said gas ket, through which holes 71. g and into screwthreadedperforations in the top of the column E there pass the shanks i ofscrews 1, whereby the plate nd gasket are fixed to the top of saidcolumn. The plate H is further provided with a central hole h only aslarge as a pin-point at the top, and thence gradually increasingslightly in diameter downward, where it is in line with the center ofthe hole g in the gasket G and the center of the vertical channel (2 inthe column E; but unlike my prior patent this top plate is notadjustable, nor is there any wall or funnel around the central hole ofthe plate, as formerly.

K represents a pin on one of the drivewheels of a locomotive; L L, thebrasses or boxes therefor; M, the strap surrounding and holding saidbrasses, and N one of the rods of the drive-wheels, the same being shownwithout any particularity of detail more than enough to show theapplication of my device thereto. The strap is provided with ascrewthreaded bore m to receive the correspondingly screw threadednipple E, and the brasses L L are bored out on top at their meetingedges above the pin K, as shown at 7.1, to receive the nipple-extensionE The operation of my improved device is substantially the same as thatof the form of oil-cup shown in my said prior patent, except that thereis no adjustment of the top plate over the column E. hen my oil'cup isat- IGO tached to the described part of the engine,

or any other part thereof having a reciproeating motion, then with eachforward or upward motion of said part the oil inside the cup is directedby the curved guide F and injected up over and onto the plate H, abovethe described minute opening it, and then as the said part of the engineto which the cup is attached moves downward or backward the whole bodyof oil in the bottom of the cup is thrown upward suddenly, therebycompressing the air above the oil and forming a compressed air-cushionin the top of the cylinder and in the recesses or openings cl b abovethe oil in the cup, which forces the oil down through the opening 71into the channel 6 e 6 directly to the part to be lubricated. This holeh is made so minute as to exclude all particles of dust, dirt, or otherforeign hole sufficing to force down the oil even if said hole does notexceed the hundredth part of an inch in diameter at the top, and byreason of the described extension E of the nipple the oil is conveyeddirectly to the part to be lubricated, thereby avoiding all danger ofits being scattered to the right and left on leaving the nipple E, asmight otherwise happen from the rapid reciprocation of the part to whichthe oil cup is attached. By the use of the soft-gasket G all necessityfor the careful grinding of the top of the column E is obviated, and atthe same time this gasket forms such a tight packing that no oil canooze out or escape from between the adjacent surfaces of said column andthe top plate H thereon.

According to the kind or quality of lubricating-oil used, the amount ofspace in the air-cushion may be varied, as required, by screwing theplug D up or down.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

matter, the pressure of the air above this 456,71&

1. In an oil-cup, the combination of the cylinder with a vertical columnhaving an oil-channel therethrough, a perforated gasket resting on topof said column, a plate with an opening of less diameter than that ofthe oilchannel and in line therewith secured to the gasket and column,and a curved guide for directing the course of the oil to said minuteopening in the top plate, substantially as set forth.

2. In an oil-cup, the combination of the cylinder with a vertical columnhaving a channel therethrough, a plate having an opening of lessdiameter than that of the said channel and in line therewith secured toand above said column, a curved guide for directing the course of theoil to said plate-opening, a closed cap having an interior openingtherein forming an air-chamber above said cylinder, and a solid recessedplug closing the upper part of said cap, substantially as set forth.

3. In an oil-cup, the combination of the cylinder with a vertical columnhaving an oil-channel therethrough, a plate having an opening of lessdiameter than that of said channel and in line therewith, a curved guidefor directing the course of the oil to said plateopening, a closed tophaving recesses or interior openings therein forming an air-chamherabove said cylinder, a nipple beneath said cylinder having anoil-channel communicating with that in said column, and a downwardprojection or extension of less diameter than that of said nipple andhaving an oil-channel -in communication with that in said nipple,

substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand, atMilwaukee, in the county of Milwaukee and State of \Visconsin, in thepresence of two witnesses.
